Description

Dedicated quick detach helping hand spanner of QMA connector

Technical Field

The utility model relates to a quick detach instrument field, concretely relates to dedicated quick detach helping hand spanner of QMA connector.

Background

The QMA belongs to one of quick connectors, is a push-in type new generation connector innovated from SMA series, is generally used for instruments, portable testers and other equipment, has high-quality electrical performance, and has a simpler and faster plug-in use design.

However, in the actual use process, it is found that the mutual connection of the QMA male and female heads of different manufacturers may cause too tight insertion and extraction force, and the QMA male and female heads cannot be simply kneaded and rapidly disassembled by fingers, or in a narrow space, for example, other shielding objects exist in the range of less than 0.5cm around the connector, the fingers cannot be completely kneaded to cause upper strength, and the QMA male and female heads cannot be smoothly extracted; more seriously, if too hard a force is applied in the above-mentioned dismantling scenario, the rf cable interconnected with the QMA connector is easily torn off, resulting in irretrievable loss.

SUMMERY OF THE UTILITY MODEL

Utility model purpose: the utility model aims at providing a dedicated quick detach helping hand spanner of QMA connector has solved current QMA connector public female head interconnect and has appeared that the plug power is too tight, can't knead the problem of disassembling fast with the finger simply.

The technical scheme is as follows: the utility model relates to a dedicated quick detach helping hand spanner of QMA connector, handle including the platykurtic, the one end tip of handle be equipped with handle integrated into one piece's quick detach head, the handle is equipped with the chamfer with the junction of quick detach head, the handle all sprays the oxidation resisting layer with the surface of quick detach head, the tip that the handle was kept away from to quick detach head is equipped with the ladder groove of U type structure, the opening in ladder groove sets up outwards.

Furthermore, a through groove is formed in the end part, far away from the quick-release head, of the handle. The through slots can reduce the weight of the handle, but do not affect the stiffness of the handle.

Furthermore, the quick-release head is of a flat structure.

Further, the length of the handle is greater than that of the quick-release head.

Furthermore, the length of the handle is 5-8 times of the length of the quick-release head. When the wrench realizes lever effect for quick release, the handle is moderate in length and convenient to grasp by a single hand; and the power arm is longer and saves more labor.

Furthermore, the thickness of the quick-release head is half of that of the handle.

Furthermore, a triangular protrusion integrally formed with the handle is arranged at the end part of the handle close to the quick-release head. The triangular protrusions serve as direction markers.

Has the advantages that: the utility model utilizes the lever principle to complete the quick separation between the QMA male and female connectors, the wrench consists of a handle and a quick-release head, the handle is mellow and moderate in length, and is convenient to be grasped by one hand; the quick-release head ingeniously simulates the finger kneading action and is matched with the lever effect, so that the use convenience of the wrench is improved; the utility model discloses can satisfy the male and female head of QMA connector under any scene and separate smoothly, both facilitate the use, reduce the associated part again and damage the probability.

Detailed Description

The invention will be further described with reference to the following figures and examples:

as shown in fig. 1 to 6, the utility model relates to a special quick-release power wrench for QMA connectors, which comprises a flat handle 1, wherein a quick-release head 2 integrally formed with the handle 1 is arranged at one end of the handle 1, a chamfer 3 is arranged at the joint of the handle 1 and the quick-release head 2, and oxidation-resistant layers 4 are sprayed on the surfaces of the handle 1 and the quick-release head 2, and the oxidation-resistant layers 4 are favorable for improving the oxidation resistance of the handle 1 and the quick-release head 2, so that the service life of the wrench is greatly prolonged;

the quick-release head 2 is also of a flat structure, a U-shaped stepped groove 5 is formed in the end portion, far away from the handle 1, of the quick-release head 2, the opening of the stepped groove 5 faces outwards, the structure of the U-shaped stepped groove 5 ingeniously simulates finger kneading action, and meanwhile, the lever effect is matched, so that the use convenience of the wrench is improved;

in the embodiment, the length of the handle 1 is 6 times of the length of the quick-release head 2, and the thickness of the quick-release head 2 is half of the thickness of the handle 1; when the wrench realizes lever effect for quick release, the handle 1 is moderate in length and convenient to grasp by a single hand; the power arm is longer and saves more labor;

the end part of the handle 1 far away from the quick-release head 2 is provided with a through groove 6, and the through groove 6 can reduce the weight of the handle 1 but does not influence the rigidity of the handle 1; the end part of the handle 1 close to the quick-release head 2 is provided with a triangular protrusion 7 which is integrally formed with the handle 1, the triangular protrusion 7 plays a role of direction identification, and the triangular protrusion 7 corresponds to the side with the larger opening of the U-shaped stepped groove 5. The utility model discloses utilize lever principle to accomplish the quick separation between the public female connector of QMA, its spanner comprises handle 1 and quick-release head 2, and handle 1 is mellow and full, and length is moderate, and the one-hand gripping of being convenient for can satisfy the public female head of QMA connector under any scene and separate smoothly, both facilitates the use, lowers the associated part again and damages the probability.
